Results
- Total weight
- 24.95 kg
- Weight per sheet
- 4.99 g
- Ream (500 sheets)
- 2.495 kg
- US bond equivalent
- 21.3 lb
- US text equivalent
- 54.1 lb
- US cover equivalent
- 29.5 lb
Formula
Sheet weight (g) = GSM × W × H ÷ 10⁶ (mm)
Bond lb ≈ GSM ÷ 3.76 · Text lb ≈ GSM ÷ 1.48 · Cover lb ≈ GSM ÷ 2.708
Assumptions & limits
- Basis weights are standard US equivalents for 500 sheets of the basic size.
Worked example
80 × 0.06237 m² = 4.990 g per A4 sheet × 5,000 = 24.95 kg.
